The Solemnity of the Immaculate Conception is celebrated on Saturday, December 8, 2018 this year. 

"The angel Gabriel was sent from God
to a town of Galilee called Nazareth,
to a virgin betrothed to a man named Joseph,
of the house of David,
and the virgin's name was Mary.
And coming to her, he said,
"Hail, full of grace! The Lord is with you."

+ Luke 1:26
